TYPE-WRITING MACHINE.

Specification of Letters Patent.

- Patented Oct. 10, 1911.

Application filed July 25, 1910. Serial No. 573,645.

To all whom it may concern:

Be it known that I, SHOBAL V. OLEVENGER,

a citizen of the United States, and a resident in typewriting machines and consists of the Y mattershereinafter described and more particularly pointed out in the appended claims. In the drawings :Figure 1 is a top plan view of my improved typewriting machine. Fig. 2 is a longitudinal section through the same on the line 22 of Fig.4. Fig. 3 is a transverse section through the movable carriage on an enlarged scale. Fig. 4: is a similar section showing the parts in that position which they occupy just prior to the printing position. Fig. 5 is a similar section showing the parts in the position of printing. Fig. 6 is a transverse section through Fig. 3 on the line 66 thereof. Fig. 7 is a bottom plan view of the universal type-carryingmember. Fig. 8 is a transverse partial section through Fig. 3 on the line 88 thereof. Fig. 9 is a detail elevation of a part of the guide-bar for the carriage showing the line-spacing mechanism. Fig. 10 is. a vertical section through Fig. 9 on the line 1010 thereof.

My improved typewriting machine embraces a base 11, upon which is supported a plate 11; a pair'of longitudinal, parallel on upright standards 13 located at the four corners of the base and braced apart at the rear by a transversely extending bar 14-; a pair of transverse guide-bars 15, 15 connected-together at their ends by means of grooved rails 16, 16'which rest upon and have guiding relationwith the longitudinal l guide-bars 12, 12 and atype-carriage 17 which is supported upon and has transverse movement with reference to the transverse guide-bars 15, 15.

As will presently appear, the letter-spading mechanism is arranged to feed the type carriage 17 from left'to right over the base on the transverse guide-bars 15, 15; while guide-bars 12, 12 supported above said base jthe planes in which said types are located,

being separated by angles of 13,-. ,in one plane are the lower case letters and .the types in the adjacent plane on the one the line-spacing is produced by the movement of the frame consisting of the transverse guide-bars 15, 15 and the longitudinal grooved rails 16, 16, which directly support the type-carriagefrom the top toward the bottom of the sheet on the longitudinal guide-bars 12, 12.

The type-carriage 17 is supported on longitudinal, parallel side bars 17', 17 which are connected to the rear transverse. guidebar 15, insuch a way as to have sliding movement thereon, said bar acting at the same time to furnish the means whereby the type-carriage may be swung upwardly away 'from the'platen, and being for this reason rotatively mounted at its ends in the longi tudinal guide-bars 12, 12.

18 is a horizontal plate provided with a central, annular opening inclosed by an upright flange 18. A shell 19, which has guiding relation within said flange 18, contains the universal type-carrying member. Said shell 19 projects above the plate 18 where it is provided with a horizontal, annular flange 19 The lower end of said shell is in the form of a hemisphere with a segment of the sphere cut away at the base so as to leave a printing opening 20 through which, as will appear, the types are projected when making a printed impression. i

21 is a universal type-carrying member. It consists of asegment of a spherical shell,

the center of which is coincident withthe center of the spherical shell119. ,On its outer surface are provided a plurality of'types 22. Said types are arranged on the surface of thetype-carrier in circular lines cut by vertical planes passing through radii of the each line, in this case three, 22, 22, 22 and The types side are the figures, punctuation marks and the like, while the types in the next adjacent plane on the'opposite side of the plane first named are the capital letters. The types 22, 22 and 22 are separated by angular intervals such that when one of said type is engaged with the platen the others will be sufliciently above the platen so as not to make a printing impression.

The type-carrier 21 is secured at its upper margin to a plate 23 which is herein sphere, there being a plurality of type in called the rosette. Said plate is provided with an edge 24 formed in the surface of a sphere adapted to closely engage the inner surface of the hemispheric shell 19". The upper face 'of said rosette is provided with a plurality of radial grooves 23 which, in

under surface of said plate is made concave,

as indicated at 27, and said under surface cuts said conical opening 25 in the plane of its smallest diameter, forming a circular bearing edge 25 which engages said upright tube 26. This construction permits the rosette and type-carrier to have universal movement-with the hemispherical shell 19,

while at the-same time providing them with a guiding relation'with the tube 26. At the upper end of the tube 26'is a horizontal annular flange 26 which engages against the under side of a plate 28 having depending flanges 28 which inclose the upper end of the shell 19 and are secured to the horizontal plate 18. Said tube 26 projects through a central opening 27. in the horizontal plate 28 and is there connected, to radial arms 29.v At the lower end of said tube are secured radial leaf springs, in this instance four in number, 30, having curved ends 30' which engage in radial grooves 31 formed on the bottom concave surface of the rosette 23. It is apparent that by means of the radial arms 29, the tube 26 may be retated on its axis,and that this rotation will,

through the springs '30, by their engagement in the grooves 31 ,be communicated to the rosette'and type-carrying memberto shift them so as tobring the capital letters or the figures into operative position.

32 is a plunger having guiding relation within the tube 26. Said plunger projects normally to a point shortly. above the upper surface of the type-carrying member 21 and at its upper end rises above the horizontal plate 28, and is there provided with a universal disk 35. A coiled spring 36 surrounds the upper end of the plunger 32-and forms an elastic cushion between the Zdis k 35 and theupper end of the tube 26.

37 is a spiral springwhich rests at its lower end against the upper surface of the plate 23 and at its upper smaller'end against the under face of the plate .28.

38 indicates a series of annularly arranged coiled springs interposed between the flange 19 of the shell 19 and the top of the plate' 18. Lugs 38, preferably formed by punching the metal of the flange 19, receive the :radial arms 29.

upper end of said springs while their lower ends are held in position by means of screws 38 threaded into the plate 18.

40 indicates a plurality of vertical typeoperating plungers. Said plungers are normally arranged in the radial plane of the lower case type, there being a plunger for each of thetype-keys in said plane, the

plungers in this instaiicebeing'arranged in sets of three, and there being nine sets of .plungers, as plainly to be seen in Fig. 6.

The lower ends of each set of three plungers are adapted when depressed to engage in .one of the grooves 23. Each plunger is provided with a shoulder 41 which is adapted at a certain point in its descent to engage against the top of the universal disk 35. When a plunger is depressed its end first engages its associated groove 23 of the rosette and shifts said rosette together with the type-carriage through a vertical angle about its'centerfThe lower end of the plunger slides through said groove as the rosette shifts and as it slides off the edge of the rosette engages in a hole 50 in the shell 19".

Itmay be said here that there is a plurality ofsaid holes arranged in sets of three directly below the plungers 40 and in the planes of the sets of types, there being a set of such holes for each set of type. This movement of the plunger shifts the typecarrier to bringthe associated type into a position above the printing position, that is to say, fromihe ."3to that of Fig. 4. I

The radial arms 29 are connected to 1011- gitudinal extending, horizontal, springposition illustrated in [fig controlled plungers 29 which are supported in lugs, 29 secured to the horizontal plate 28. By means of said plungers the arms 29 are arranged to be shifted angularly through an angle of 1319, thereby shifting the type-carrier 21 on its vertical axis and with it the rosettev 23, so as to bring one or the other of the sets of type arrafigedin planes of 13 at either side of the planeof the lower caseinto a posit-ion below the key plunger 40, depending upon which plunger isoperated. 29.5 are. stops secured to the plate 28 for limiting'the movement of said Springs 29 return. 'the radial arms 29 to their initial position when the pressure is removed from the shift keys 29 located at the outer ends of said plunge 2 5 The operation of'the improved typewriting machine is as follows Su ppose it is desired to print the type lower case a, indicated by the numeral 22. The outer left-hand plunger as shown in Figs. 3, 4 and 5, is depressed. The lower end of said plunger engages in the groove 23 of the rosette 23 and as it vcontinues to descend, shifts said rosette and with it the type-carrier so. as to rotate it through a vertical angleabout its center until the lower end of said plunger 40 slides off. of the end of said rosette, whereupon the continued depression of said plunger 40 Y in connection with my machine.

brings its end into engagement with the associated hole '50 in the shell 19". At the same instant, the shoulder 41 on said plunger engages against the universal disk The parts how are in the position'indicated in Fig. 4, with the type 22 in vertical position abo e the printmg'position. The descent of the type-plunger below this point presses the plate 35 and with it the plunger 32, so that the lower end of said plunger 32 engages the uper face of the printing typecarrier 21 and forces the type into printing engagement with the paper on the platen, as indicated in Fig. 5. .IVhen the key is released, the several springs return the parts to their normal initial position.

Any suitable mechanisinmay be employed for depressing the type plungers and for returning them to their initial position. No such means is shown herein as it forms no part of the present inventi n.

. Any convenient inking device may be used As shown in the drawings, 42 is an ink ribbon which has guiding relation with the rollers 43 secured tothe outer face of the spherical shell 19 at each side of the printing opening 20. Said ribbon extends under said printing opening and its ends are wound on drums 44, 44 which are supported by means of suitable standards 45, 45 on the shell 19. One of said drums is provided with a ratchet 46 adapted to be engaged by a swinging gravity pawl 47 hinged tothe lower'side of the plate 18 when the shell 19 returns to its initial position after it has been depressed in maktype-carriage transversely on the transverse guide-bars 15, one letter space each time the shell 19 is depressed in the printing operation. 52 is a spacing key or bar. It is rigidly connected to longitudinal, hinged arms 52 provided with diametrically opposed depressions 52 which are adapted to engage the horizontal flange 19 on the shell 19 and depress the same, thus operating the escapemechanism when a key-plunger is not depressed.

To provide for line-spacing one of the guiding-rails 12 is provided with a series of holes or recesses 12 longitudinally separated by a space equal to the space of one line. Hinged to the associated grooved rail 16 on the type-carriage is a spring-controlled lever 12" having a detent 12 adapted to engage in one-of said recesses 12 It is apparent that by manipulating said lever the frame including the transverse guide-bars 15, 15 and he grooved rails 16, 16 may be fed down the sheet by hand to bring it to successive positions separated by line spaces.

In order to provide an adjustment to take care of papers of different thickness and also so that the machine may be used on books, where the level of the sheet above the platen will vary, I prefer to. make the frame which carries the type-carriage adjustable in a vertical direction above the platen. To this end the longitudinal guide-bars 12 are mounted in vertical slots 18? in the standards 13 and are adapted to be locked at the desired level by means of set screws 13".
